The required sample volume is at least 1.5 litres, plus an additional 0.5 litres of preserved water sample (for which you can pick up the plastic bottle containing the preservative at the Dinax Ltd. shop before sampling).

For the measurement of the other parameters, we recommend to take the sample in a clean, carbonated mineral water bottle, rinsed several times with the sample and filled to the top.

The maximum storage time of the sample (from sampling to testing) is 24 hours, but it is advisable to take the water sample immediately before leaving for our shop and to store it refrigerated - for reliable results.

Please bring your water samples to the shop by 12.00 noon on Wednesday each week.
